El 20 de diciembre, a las 12h, en la Sala 2304 (Escuela de Ingenierías Industriales, sede Mergelina), Carlos Méndez, profesor en la Universidad Nacional del Litoral e investigador en el CONICET (Argentina), impartirá una conferencia titulada:
“Towards Advanced Optimization Models for Power-Intensive Processes under Time-Sensitive Electricity Prices”
Abstract: The competitiveness of power-intensive industries is highly tied to their ability to adjust production according to time-sensitive electricity prices. A classic example are Air Separation Units (ASUs), where large, electric-power air compressors are used to reach cryogenic temperatures. Due to the volatility nature of the energy markets, there is significant opportunity to reduce production costs by scheduling production during the cheapest hours of the day. Mixed-integer linear model (MILP) based on a discrete-time scheduling formulation can be used to represent and optimize operating decisions for any process under time-sensitive energy prices. The main goal is to find an optimal production schedule over a given time horizon that guarantees product demand satisfaction and that minimizes total energy cost. The formulation can be used to model transitions between operating modes results in a very efficient and robust model. The model is applied to a simplified industrial case. The results show optimal solutions for the proposed methodology with modest computational effort.
